Archaeologists use two kinds of dating methods: relative dating and absolute dating. In relative dating, we determine which things are older or younger based on their relationships. For example, we know from geology that soil layers near the surface of the ground are usually younger than those deeper down. This relationship helps archaeologists know that objects we find deep in the ground are older than things we find closer to the surface.All isotopes of carbon have 6 protons but different numbers of neutrons. One of the carbon isotopes that occurs in nature is radioactive; it has 8 neutrons and is called carbon-14.

Answer:

The skin looks the same because of the amont of melanin and since the amount of melonin might not change exept in a few cases.

Here is an explanation

Explanation:

Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells. In human bodies, nearly two trillion cells divide every day.

A VARIETY of softening techniques have been used to prepare hard material sections for microscopic examination, but none of them have been found to be effective for so-called "improved wood," which is made up of wood-resin compressed and bonded at a high temperature while being impregnated with phenol-formaldehyde or another resin.

The composition and distribution of fillers, coloring agents, reinforcements, and other internal structural characteristics can be determined by microscopic study of synthetic wood-resin and products containing such resins. It can also be used to distinguish between the various resins that are used as adhesives in plywood1. Some researchers have turned to the petrologists' method of grinding and polishing thin sections for examination by transmitted light and the metallurgists' way of studying a polished surface by reflected light in order to make microscope sections of the tougher forms of these materials.

Answer:

B

Explanation:

The Carbon Cycle is the cycle of where carbon is circulated all over, from the atmosphere to Earth, and back. Our planet is a closed environment thanks to our atmosphere, and so the density and amount of Carbon in circulation is always the same. Carbon is released to the never ending cycle by volcanoes, fossil fuels, and other natural processes. Most of the Carbon on Earth is stored in rocks and the ground, while the rest is everywhere else.

Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A

Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.

One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.

EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.

Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.

While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

Explanation:

Answer:

Three diseases/disorders caused by mutations:

If structure E (stapes) lost flexibility, it would impair sound transmission, leading to hearing sensitivity.

Process of hearing: Sound waves enter the ear, vibrate the eardrum (tympanic membrane). Ossicles (A: malleus, B: incus) amplify vibrations to inner ear. Vibration of fluid in cochlea stimulates hair cells, converting to electrical signals for interpretation.

Structure A: Malleus

Structure B: Incus

(a) Structure C (eustachian tube) equalizes pressure on both sides of the tympanic membrane.

(b) Structure D (round window) absorbs excess pressure waves from the inner ear.

https://brainly.com/question/13025218

#SPJ8

Hearing involves a process of sound wave transduction through the tympanic membrane and ossicles. If the tympanic membrane (E) loses its flexibility, sound quality may diminish. The Eustachian tube and cochlea serve to manage pressure within the ear.

The process of hearing (audition) involves the transduction of sound waves into a neural signal. When the tympanic membrane (structure E in your diagram), or eardrum, is struck by sound waves, it vibrates. These vibrations are then transferred to the ossicles, which are three small bones in the middle ear. The ossicles are identified as structures A (Malleus or Hammer) and B (Incus or Anvil) in your diagram. Sound waves are finally transduced into a neural signal in the inner ear.

If the tympanic membrane was to lose its flexibility, it would not vibrate as effectively when struck by sound waves. This could diminish the quality of sound and potentially lead to hearing loss.

The Eustachian tube equilibrates air pressure on both sides of the tympanic membrane. This would be your answer to part (a) of the lettered question. Part (b) refers to the role of the cochlea in the inner ear, which helps to absorb excess pressure waves from the inner ear.

The correct option is mammals, like Dall sheep.

A survivorship curve refers to a graph showing the number or proportion of individuals surviving to each age for a given species or group. There are three types of survivorship curves as follow:

Type I curves depict individuals that have a high probability of surviving to adulthood. For example,  large mammals have type 1 survivorship curves, because they have a. low infant mortality and high rates of survival into old age.

Type II curves also called as intermediate type, it depict individuals whose chance of survival is independent of age. For example, most birds have type 2 survivorship curves birds die more or less equally at each interval of their age.

Type III curves depict individuals that mostly die in the early stages of their life. For example, Trees, small mammals, some birds, oysters, shell fish, many insects, oak tree and fishes exhibit type 3 of survivorship curve because in these species mortality rate is high during the early stages of life.

Small plants, like Cleome droserifolia is a herbaceous perennials also typically display Type III survivorship curves, with a very low seedling survival and a low initial life expectancy,

Once water is in the xylem, it travels upwards - against the force of gravity - towards the rest of the plant. Water is able to move against gravity due to two forces: tension and cohesion. Tension is a 'sucking force' which is created when water evaporates from leaves (transpiration), pulling more water into the leaf.

Explanation:

Movement of Water and Minerals in the Xylem. Most plants obtain the water and minerals they need through their roots. The path taken is: soil -> roots -> stems -> leaves. The minerals (e.g., K+, Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).
